However, • Finding the exact position of an active fault. • Secondary ruptures may develop increasing the complexity of the problem. • Soil conditions over a fault also influence its behaviour leading to bifurcation and deviation. • It is difficult <strong>for</strong> large infrastructure like bridges, tunnels, pipelines and roadways to avoid crossing a potential fault, if its position is dictated by other factors.
